摘　　要：基于高速公路路基压实均匀性的检测和评估,结合智能压实技术,探讨了压实计值(CMV)与传统压实度、CBR等指标之间的相关性。通过在不同试验段进行实地检测,采用主成分分析(PCA)方法对路基压实的均匀性进行综合评价,进一步验证了CMV与CBR指标在评估过程中的互补性和一致性。研究结果表明,CMV与CBR指标之间具有较高的相关性,二者能够有效反映路基压实的均匀性。在实际工程中,通过综合运用这些指标,可以更加准确地评估路基压实质量,并为改进施工质量、提升路基稳定性提供有力支持。研究还提出了一套基于主成分分析的压实均匀性评价体系,可以有效量化路基压实的均匀性,为未来的公路施工和养护工作提供理论依据和技术支持。In this paper,based on the detection and evaluation of compaction uniformity of highway subgrade,combined with intelligent compaction technology,the correlation between CMV and traditional compaction degree,CBR and other indexes is discussed.Through field testing in different test sections,Principal Component Analysis(PCA) method is used to comprehensively evaluate the uniformity of subgrade compaction,and further verify the complementarity and consistency of CMV and CBR indexes in the evaluation process.The results show that there is a high correlation between CMV and CBR indexes,which can effectively reflect the uniformity of subgrade compaction.In practical engineering,the comprehensive application of these indexes can more accurately evaluate the compaction quality of the roadbed,and provide strong support for improving the construction quality and improving the stability of the roadbed.A compacting uniformity evaluation system based on principal component analysis is also proposed,which can effectively quantify the compacting uniformity of roadbed and provide theoretical basis and technical support for future highway construction and maintenance.
